DESCRIPTION:
The FCT3245/A octal transceivers are built using ad-
vanced dual metal CMOS technology. These high-speed,
low-power transceivers are ideal for synchronous communi-
cation between two busses (A and B). The direction control
pin (DIR) controls the direction of data flow. The output enable
pin (
OE
) overrides the direction control and disables both
ports. All inputs are designed with hysteresis for improved
noise margin.
The FCT3245/A have series current limiting resistors.
These offer low ground bounce, minimal undershoot, and
controlled output fall times-reducing the need for external
series terminating resistors.
